11.Which of the following, if true, is the most logical completion of the argument below?
The tax system of the Republic of Grootland encourages borrowing by granting its taxpayers tax relief for interest paid on loans. The system also discourages saving by taxing any interest earned on savings. Nevertheless, it is clear that Grootland's tax system does not consistently favor borrowing over saving, for if it did, there would be no--.
(A) tax relief in Grootland for those portions of a taxpayer's income, if any, hat are set aside to increase that taxpayer's total savings
(B) tax relief in Grootland for the processing fees that taxpayers pay to ending institutions when obtaining certain kinds of loans
(C) tax relief in Grootland for interest that taxpayers are charged on the unpaid balance in credit card accounts
(D) taxes due in Grootland on the cash value of gifts received by taxpayers from banks trying to encourage people to open saving accounts
(E) taxes due in Grootland on the amount that a taxpayer has invested in interest-bearing savings accounts

why A????

原本的意思是这个地基儿对借债是鼓励的，因为还息的钱可以免税，同时不鼓励储蓄，因为储蓄的利息收税，然而，它又不是一成不变的对借债优惠而对储蓄不鼓励，因为如果这样，就不应该存在，不应存在的东西一定是优惠储蓄的，那么A 是最佳选择
